Parametric Study on the Free-Fall Water Entry of a Sphere by Using the RANS Method
Journal of Marine Science and Engineering, 2019 Motivated by the application of water-entry problems in the air-drop deployment of a spherical oceanographic measuring device, the free-fall water entry of a sphere was numerically investigated by using the transient Reynolds-averaged Navier−Stokes

Ship Loading Influence on the Slamming Impact of Typical Sections of an S-175 Container Ship
Journal of Marine Science and Engineering, 2020 This paper investigates the influence of ship-loading condition on slamming during water entry. Three typical sections of the S-175 container ship, namely the bow, parallel middle body and stern, under three different loading conditions are studied. Full-

An experimental investigation into the constant velocity water entry of wedge-shaped sections
, 2008 Constant velocity water entry is important in understanding planing and slamming of marine vessels. A test rig has been developed that drives a wedge section with end plates down guides to enter the water vertically at near constant velocity. Entry force

Research on Water-Entry Hydrodynamics for a Cross-Wing Underwater Vehicle
Journal of Marine Science and EngineeringThe optimization of the water-entry strategy for cross-wing underwater vehicles has become a research hotspot in the field of engineering, and its water-entry process is quite different from that of wedges and cylinders. In order to address this problem,
